Personally, I wouldn't bet on that ;), but there must be a bug somewhere,
I get the same result as Werner (with Saxon, Transformiix and MSXML3).

There are a few oddities in your stylesheet, but they shouldn't cause 
any exception.
The exception details you posted point to "line 60", is that the 
xsl:for-each with
the xpath David suggested? There is nothing wrong with that xpath (I bet 
on that :).
But how can it be line 60 in such a short stylesheet?

About the stylesheet: I think you misunderstood one of my previous 
messages (with the xsl:apply-templates).

   <xsl:template match="Documents">
       <xsl:apply-templates select="*[@filter='' or @filter=$filter]"/>
       <Documents>
           <xsl:for-each select="Document[@filter='' or 
@filter=$filter]/Article[count(.|key('by-info',@info)[@filter='' or 
@filter=$filter][1])=1]">
               <Document name="{@info}">
                   <xsl:copy-of 
select="key('by-info',@info)[@filter=$filter]"/>
               </Document>
           </xsl:for-each>
       </Documents>
   </xsl:template>

The xsl:apply-templates select="*[@filter='' or @filter=$filter]" will 
do nothing,
because there is no template match="Document" in the stylesheet.
You better remove that line (although it should not influence the result).

I would advise you to try out a different processor, if only for debugging.
Instant Saxon is very good and it's free:
